Serviceguard for Linux

Hi,

I am trying to set up a 2 node serviceguard cluster on RedHat Linux 3ES (AMD 64 bit) and get an error regarding saying that cluster lock lun is different between the nodes.

Error: Physical lock lun device "/dev/sdb1" on node "luxmqpri" does not correspond to the same device as the physical lock lun device "/dev/sdb1" specified for node "luxmqsec". It cannot be used for cluster lock.Error: Invalid data for cluster lock LUN configuration

I know this is the same device, there are only 6 EMC disks and it is the only available disk that has this disk partion.

I have setup the small partition in Linux (mode 83) and confirmed this from both nodes.

Re: Serviceguard for Linux

Thanks for your mail David but I found the cause of the problem last week and had forgotten to close the thread (oops). I was pointing to the correct disk but the EMC array had a setting to send the channel number back to the server. The probe used by serviceguard saw the disk as 2 seperate disks although LVM considered them to be the same disk. A change on the EMC array and all is good in my little world.James.
